About the Japanese Language

Japanese spoken as a native language by 128 million people around the globe, primarily Japanese people in Japan, ranking as the ninth most spoken language in the world.

There are two main differences between legal and sworn translations:

In sworn translation, a sworn translator must be certified by the government and swear an oath to the accuracy of the translation. In legal translation, a legal translator does not have to be certified by the government, thus significantly reducing the translation cost.

Another big difference between legal and sworn translations is that sworn translation is often used for official documents that are legally binding in another country, such as birth certificates. On the other hand, legal translation is used for documents more relevant to business purposes or for legal proceedings within one country.
